Why are participants “randomized” in some clinical trials?
In clinical trials where there is both a study group and a control group, participants are assigned to either group by chance. This process is called “randomization.” Patients are randomized to avoid study bias. Randomization is used to help ensure that study results are influenced only by the study drug being tested. Your Doctor and the Clinical Trial Is a referral from my physician required for participation in a clinical trial? No, you do not need a referral. It is up to you to decide if you wish to participate or not. However, participants are usually encouraged to discuss participation in the study with their own physician and their family. In order to participate in a clinical trial, you will be evaluated by the medical staff conducting the study to determine if you meet all the medical criteria. If you are eligible, the details of the trial will be explained to you. Can clinical trial participants still see their regular doctor? Yes. Clinical trials do not replace normal health
